Answer 1

1.“三分之二”的庄稼，是单数！

3.students是复数，这叫“就近一致原则”

我告诉你方法如下：
①语法一致原则，即谓语的单、复数形式依主语
的单、复数形式而定：主语为复数，谓语动词用复数；主语为单数或是不可数名词，谓语动
词用单数。
②就近一致原则，即谓语动词的人称和数要与它最邻近的名词或代词保持一致。
③意义一致原则，即不以语法形式而从意义着眼处理一致关系，若主语形式上为复数，但
意义上是单数，谓语动词需用单数；若主语形式上为单数，而意义上是复数，则谓语动词用复数

Answer 2

1.将三分之二的庄稼看作一个整体。
2。这个应该是时态问题。一般过去时。
3。none作主语的句子谓语动词可单可复，所以可以用has。
4。同1题。
5。根据后面题意，这里应该是一般将来时，所以用will tell。
6。应该是单数，所以不能用are。
7。 前面should have done表示应该做但没有做的事情，也就是说过去了，所以后面用过去时，表示没有被邀请。
8。rather than 后面用动词ing形式。
9。并列从句中，第二个关系词不能省略。

你的问题好多，但是我喜欢回答相关问题。望采纳。
